So our total volume size is still 32 gigabytes. Go ahead and click Next. We'll assign that a drive letter of E, click Next, then we have to format the volume, and we'll just use NTFS with a default allocation unit size and we'll give it a name of Mirrored. And we'll perform a quick format to save time, click Next, and then Finish, and then we'll wait a minute while the new mirrored volume is formatted. Alright, the new mirrored volume has been created and File Explorer pops up showing us the contents of the new drive. We click on This PC, we see that we have a new drive here called Mirrored. Now, if I were to open up this drive, right click, and say "new bitmap image." When I just created that file that file was actually written redundantly to both disk one and disk two. A copy of that same file exists on both of these hard disk drives. That way if for some reason disk Two goes offline, maybe the hard drive goes bad or something like that or it comes unplugged, the redundant copy will still be available on disk one and we'll be able to access the data. So, that's how you create a mirrored volume in Windows. Creating a Striped Volume 5:23-9:07 Let's do the same thing now to create a striped volume. I'll come down here to disk three, right click,and select New striped volume. As we said earlier, a striped volume is the equivalent of a RAID zero volume. I'll click Next. Now because I right clicked on disk three when I selected Create new striped volume, disk three's automatically added to the select column. Now in order to create a striped volume I have to have two drives. To stripe data across, I'll click on disk four and click Add. Now notice that things are a little bit different down here under total volume size as opposed to what we saw with the mirrored volume. Notice that the size of the volume is now equal to the sum of the two disks, disk three and disk four.Remember with a mirrored volume it was only the size of one of the disks. Now with the striped volume it's the size of both disks. So with striping what we're essentially doing is taking data that's being written to the volume and we're breaking it up into chunks and we're writing those chunks to both disks in the volume at the same time. Now we're not writing them redundantly like we did with mirroring. Instead, we're spreading that data equally across the two disks in the volume, in this case disk three, disk four. The advantage of doing that is that it really increases performance because we're essentially writing with two different controllers at the same time. Therefore, disk writes take considerably less time than they do with say a standard volume or mirrored volume. And likewise when we read, we read from both disks at the same time. So once again, read operations are a lot faster. The danger, however is the fact that we have taken the data and spread it across both of these hard disk drives. That means if one of these disks, such as disk four, were to go down then all of the data on the volume would be lost because half of each file would've been lost on disk four. So disk mirroring provides redundancy and safety without any

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
